Fixtures

The present invention provides a fixing device, in particular, a fixing device for temporarily locking and locking the floating sleeve and the locking body, and is fastened inside the base for the locking body to be worn, and the locking body is outside the cap. The rotating sleeve is assembled to drive the rotating rod of the button body to expand and contract in the base.

When the general panel (board-to-board) is combined, it is locked by a positioning screw equipped with a knob, a collar and a screw, and the screw and the collar are fixed on the first panel, and the knob is rotated. The screw is locked in the second panel to form a preset position, and then the hand tool is used to lock the screw, so that the first panel and the second panel are locked and fixed into one body, and can be used in a telecom cabinet, an industrial computer, and a work. The mother machine or the like uses a device composed of a plurality of devices and a mechanism to perform a board-to-board connection.

Furthermore, please refer to the eleventh figure, it can be clearly seen from the figure that the cap A is embedded with the screw A1 with the nut A11, and the elastic body B is sleeved on the screw A1. The cap A and the elastic body B are assembled on the joint C, and the inner hook A2 at the lower side of the cap A is engaged with the flange C1 at the top end of the joint C, thereby the cap A and the elastic body B can be And the connecting seat C is formed into a positioning device D, and then the locking device C2 of the positioning device D at the bottom end of the connecting base C is embedded and fixed in the positioning plate body E, and then the screw A in the cap A can be used by using a hand tool. 1 Locked into the fixed plate body E1, thereby achieving the purpose of locking the fixed plate body E and the fixed plate body E1, and after the user removes the fixed plate body E1, the positioning device D can still be fixed by the connecting seat C It is positioned in the board E without loss.

However, in the case of the increasing popularity of equipment such as cabinets, industrial computers, and work machines, the use of the screw A1 to lock the positioning plate E and the fixed plate E1 is easy to be operated and used. The limitation allows the user to spend more time and manpower on the disassembly and assembly work, which is not convenient for quick disassembly and assembly, and the screw A1 in the cap A also needs to be locked into the fixed plate body E1 by using a hand tool. If the user neglects to carry the adapted hand tools, it will seriously affect the overall disassembly and assembly work. Not only is it time-consuming and inconvenient, but also the cost of working hours will increase, and those who have yet to work in this industry will redesign them. Effectively solved.

Therefore, how to solve the problem and lack of hand tools that must be used in the assembly or disassembly of the body, and the positioning device is in a floating state, and it is easy to swing and dump when it is to be fixed on the positioning plate body, and it is not suitable for the fixed operation. Trouble and trouble, must be improved, that is, the creators and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the problems and deficiencies in the use of conventional fixtures, the creators have collected and reviewed relevant materials through multiple assessments and considerations, and have used the years of R&D experience in the industry to continuously try and modify them. The birth of a new patent for a fixed device that facilitates the smooth operation of a fixed operation.

The main purpose of the present invention is that the fixing device is provided with a through hole and a receiving space in the base, and the outer surface is formed with a plurality of guiding portions arranged in a misaligned position and a blocking portion having a large outer diameter. And two or more channels are arranged adjacent to the blocking portion at the guiding portion, and the plurality of grooves are opposite, and the rotating rod of the cap head of the locking body is disposed in the through hole, and The rotating rod sleeve is provided with two sides of the elastic body to abut against the cap head and the inner wall surface of the accommodating space, and the other side of the rotating rod is movable and contracted inside and outside the through hole of the pedestal, and is assembled outside the cap of the locking body. The sleeve is sleeved to be sleeved outside the base, and the inner wall surface of the socket space is provided with a plurality of snap ribs for a plurality of grooves on the outer surface of the base to transmit the sleeve Driving the locking body, and the plurality of locking ribs of the rotating sleeve can be rotationally displaced along the guiding portion to the other groove to abut against the blocking portion, and at the same time, the locking portion of the locking body is buckled The locking state is formed at the limiting slot of the second plate body, and the bushing can be temporarily used to lock the locking body in the base without shaking, and when the fixing device is positioned on the preset plate, the fixing device is not stable.
